Special Commands for PrehKeyTec Devices
With the following commands you can control the PrehKeyTec devices and their internal modules. For
an easy implementation into your Windows application, you should use our MWXUSB.DLL or
OPOS/JavaPOS packages. These can be downloaded from our website. See the included
documentation for details.

Important note:
•
Above internal low-level commands should not be used unless we advise to do so.
•
You should always prefer to use high-level functions of our MWXUSB.DLL or OPOS/JavaPOS.
•
Above commands might not be available for every PrehKeyTec device. Especially older keyboard
models do not support newer commands at all.
•
Using such low-level commands on old keyboards will result in unpredictable behaviour.
